Fills the array with the information about points that are closest to the received point.
IppStatus ippsGetVarPointDV_16sc(const Ipp16sc* pSrc, Ipp16sc* pDst, Ipp16sc* pVariantPoint, const Ipp8u* pLabel, int state);
pSrc |
Pointer to the reference point in format 9:7 |
pDst |
Pointer to the closest to the reference point left and bottom complex point in format 9:7 |
pVariantPoint |
Pointer to the array where the point information is stored |
pLabel |
Pointer to the table that stores the labels. |
state |
Number of states of a convolution coder. |
The function ippsGetVarPointDV is declared in the ipps.h file. This function fills the specified array pVariantPoint with the information about 2D complex points that are closest to the reference point pSrc. This information includes the corresponding labels from the offset table and calculated errors. The number of possible states may be 16, 32, and 64. The number of points in the array depends on the number of states: if state = 16 , then 4 points will be referenced in the array, if state =32 or 64, then 8 points will be referenced.
ippStsNoErr |
Indicates no error. |
ippStsNullPtrErr |
Indicates an error when any of the specified pointers is NULL. |
